Detect when `writer_is_dead' also when the writer is some other user.
From Karl Heuer.
(parse_options): Warn if --pid=PID is used without -f.
|
|
|
|
(pid): New global.
(long_options): Add `pid'.
(usage): Describe it.
(tail_forever): Implement it.
(parse_options): Handle the new option and required arg.
Suggestion and pseudo-code from Karl Heuer.

|
(dd_copy): Use those to page-align both the input and output buffers.
|
|
(write_counts): Use it to select printf formats.
(main): Set posixly_correct from the POSIXLY_CORRECT envvar.
From Peter Moulder.
|
|
(ROUND_UP_TO_MODULUS): Define.
(dd_copy): Page-align the input buffer.
Based on a patch from Scott Lurndal.

Remove a couple unnecessary FIXME comments.

document. Change all uses and locals like was_missing to was_tailable.
Invert expressions as appropriate.
(reopen_inaccessible_files): Rename from allow_missing.
(sleep_interval): Describe.
(--allow-missing): Deprecate.
(--retry): New option, equivalent to --allow-missing.
(usage): Document name vs. descriptor differences.
Refer to manual for descriptions of --max-unchanged-stats=N
and --max-consecutive-size-changes=N.
(valid_file_spec): New function.
(recheck): Assert valid_file_spec.
Remove dead else-if block (suggestion from Eli Zaretskii).
Adjust stmts that set f->tailable -- unlike for `missing', tailable
doesn't depend on errno == ENOENT.
(parse_options): Give a warning if --retry is used when not following
by name.
|
|
(recheck): Record the new value of errno in f->errnum. Don't
output an error message unless the new value of errno differs from
the old one. Output a message if previously-inaccessible file
becomes accessible.
(tail_forever): Always recheck files whose fd is negative. If the
file cannot be fstat'ed, record the errno value in f[i].errnum.
(tail_file): If the file cannot be open, record the errno value in
f->errnum. If it can be opened, initialize f->errnum to zero. If
it's a non-regular non-fifo file, initialize f->errnum to -1.

Include hard-locale.h, linebuffer.h, memcoll.h.
(struct line): New member `buf', replacing `beg' and `lim'.
All uses changed.
(hard_LC_COLLATE): New var.
(main): Initialize it.
(get_line): Use readline to read the line,
instead of doing it by hand.
That way, we get a buffer that we can pass to memcoll.
(keycmp): Use memcoll to compare lines if hard_LC_COLLATE is nonzero.
|
|
(hard_LC_COLLATE, hard_LC_CTYPE, hard_LC_TIME): New variables,
replacing `need_locale'.
(memcoll): Move to lib/memcoll.c.
(keycompare): No need to alloc (0), since our caller now does it.
(compare): alloca (0) before returning.
(my_setlocale): Remove; hard_locale now dows this.
(main): Invoke setlocale, bindtextdomain, and textdomain before
invoking anything that might print an error.
Use hard_locale to determine which locales are hard.
|
|
(hard_LC_COLLATE): New variable.
(compare_files): Use memcoll to compare if hard_LC_COLLATE.
(main): Initialize hard_LC_COLLATE from locale.
|
|
Use size_t, not int, for lengths.
Lines now contain trailing newline.
Adapt for readline changes.
|
|
(writeline): Lines now contain trailing newline.
(check_file): Use size_t, not int, for lengths.
|
|
|
|
|
|
|
|
(df_readable): Take ceiling if posix_format.
(ceil_percent): New function.
(show_dev): Take ceiling of percent if posix_format.
Align with POSIX-conforming header if posix_format.
|
|
Otherwise, `mv' would not preserve the permissions when copying
between partitions. Reported by David Godfrey
|
|
Add a single condition to the existing sameness test.
|
|
(copy_internal): Qualify SAME_INODE test with (link-count == 1
|| same_name(...)).
|
|
<same.h>: Include this instead.
<dirname.h>: No longer include this.

first, not last, to be consistent with -M.
|
|
(general_numcompare): Use strtod, not xstrtod.
Do not consider partial conversions to be errors.
Put -infinity at the start, and +infinity at the end;
follow +infinity with NaNs (sorted by bit pattern),
and finally by conversion errors.
|
|
(struct line, findlines, compare, checkfp, mergefps, sort):
A line now includes its trailing newline.
(findlines): Do not replace newline with NUL.
(memcoll, keycompare): Work even if the data to be compared are
adjacent strings; this is possible now that lines contain the
trailing newline.
(fillbuf): Always have an unused byte at the end of the buffer,
since memcoll and keycompare want to modify a byte after the last line.
(sortalloc, mergealloc): Increase by 1, for trailing byte.
|
|
localized comparison says the strings are equal.
|
|
characters properly when comparing with LC_COLLATE semantics.
(NLS_MEMCMP): Remove.
(memcoll): Renamed from strncoll.
Take separate lengths for each string.
This function is now invoked only when need_locale.
(keycompare): Don't copy strings when ignore and translate
are both NULL.
|
|
is also changed. Define to const also if !HAVE_NL_LANGINFO.
(usage): `,' -> `;' (English typo).
|
|
input files are also read in binary mode.

months, as this conflicts with POSIX.2 and is tricky to boot.
(FLOATING_COMMA, NLS_STRNCMP, NLS_MAX_GROUPS,
NLS_ONE_CHARACTER_STRING): Remove macros no longer used.
(nls_grouping, nls_fraction_found, nls_month_found, nos_monthtab,
nls_months_collide, nls_keyhead, us_monthtab): Remove variables no
longer used.
(struct nls_keyfield): Remove types no longer used.
(strncoll_s2_readonly, nls_set_fraction, look_for_fraction,
nls_month_is_either_locale, nls_numeric_format): Remove functions no
longer used.
(monthtab): Now has the role that us_monthtab had, but it's const only
if ENABLE_NLS is not defined.
(C_DECIMAL_POINT): Renamed from FLOATING_POINT. All uses changed.
(MONTHS_PER_YEAR): Renamed from NLS_NUM_MONTHS. All uses changed.
(struct_month_cmp): Renamed from nls_sort_month_comp. All uses changed.
Use strcmp, not strcoll, since the user doesn't care about collating
here.
(inittables): Read locale data into monthtab, rather than modifying a
separate month table and futzing with indirection. Do not worry about
colliding months, since we no longer autodetect month locale.
(fraccompare): Don't set no-longer-used variable nls_fraction_found.
(getmonth): Use strncmp to compare months, since user doesn't care
about collating here. Fix bug where code incorrectly assumed that
strlen (monthtab[lo].name) == strlen (monthtab[ix].name).
(keycompare, main): Don't autodetect month locale.
(compare): Don't use NLS_MEMCP in code that can't be executed if
need_locale is false, as NLS_MEMCP is equivalent to memcmp in that
case.
(sort, insertkey, main): Don't autodetect numeric locale.
